Abstract :

Metal-containing polymers are of considerable industrial interest; they are currently being used in molecular electronics, solar panels and catalysis. In addition, organometallic complexes such as Cr(CO)6, (├?┬Ě6-C6H6)Cr(CO)3 and (├?┬Ě5-C5H5)2Fe, when embedded in polymers, are used as infrared spectroscopy calibrants, photo-initiators for styrene polymerization and light absorbing layers in imaging devices, respectively. When subjected to high pressures, polymeric materials can evidence changes in molecular orientation, local chemical structure and even form new phases. With these possibilities in mind, we have investigated the effect of high mechanical pressures on the infrared and Raman spectra of poly(methylmethacrylate) (PMMA) and some organometallic complexes, e.g., Cr(CO)6, (├?┬Ě5-C5H5)Mn(CO)3 and (├?┬Ě6-C6H6)Cr(CO)3, embedded in PMMA, up to ~70 kbar (70,000 atm) with the aid of a commercial diamond-anvil cell. The experimental aspects of these measurements will be described and the results obtained will be discussed.
